Tips for Measuring Your Finger
- Measure at the end of the day when your fingers are warm and at their largest.
- Measure 3 to 4 times for maximum accuracy.
- Ensure the sizer can slide comfortably over your knuckle.
- If you fall between two sizes, we recommend ordering the larger size.
Tips for Sizing Someone Else
- Borrow a ring they already wear on their left ring finger.
- Trace the inside of the ring on a piece of paper.
- Ask their friends or family if they happen to know the size.
- When in doubt, aim slightly larger—it's easier to resize down than up!
How to Find Your Ring Size for the Perfect Fit
Your ring should fit your finger comfortably—snug enough so that it will not fall off, but loose enough to slide over your knuckle with some resistance. Finger size changes depending on the time of day and the weather. For best results, measure your finger size at the end of the day when your fingers are warm.
The Importance of Getting Your Ring Size Right
A perfectly sized ring means security and comfort. A ring that is too loose risks slipping off, especially in cold weather. A ring that is too tight can cause discomfort and swelling. If you are purchasing an engagement ring, taking the extra time to ensure the size is correct will make the proposal moment flawless.
